In the present work, several mechanisms of four bars for knee prosthesis were studied and
evaluated. We compared and defined the design parameters as well as an optimization …

The transfemoral amputation involves the loss of the knee joint, which is recognized as a
common and complex case. The knee is replaced by a polycentric mechanism, which is …

In this article, we have designed an active prosthesis for the lower limb of a human. The
unique design incorporates an exoskeletal extension that serves as a low-cost sensory …

In the present investigation, the design and simulation of a polycentric knee mechanism with
four-bar of voluntary control is performed, posing its mathematical model using the vector …

Original scientific paper Intelligent bionic leg (IBL) controlled by magneto-rheological (MR)
damper is an advanced prosthesis. The structure of human knee joint and torque control …

The aim of this work is to show the results of the stress analyses performed during the
structural design of a polycentric knee prosthesis. This was done by means of the finite …
